SH EET-M ETAL CAN.

SPECIFICATION forming part of Letters Patent No. 225,499, dated March16, 1880.

Application filed September 25, 1879.

To all whom it may concern:

Be it known that I, FRANCIS A. WALSH, of Chicago, in the county of Cookand State of Illinois, have invented new and useful In]- provements inSheet-Metal Cans; and I declare the following to be a full, clear, andexact description thereof, which will enable others skilled in the artto which my invention appertains to make and use the same, referencebeing had to the accompanying drawings, in which- Figure 1 represents avertical section, in de tail, of a sheet-metal can embodying myinvention; and Fig. 2 represents a vertical elevation of the completedcan, partly in section.

Like letters of reference indicate like parts.

My invention relates to that class of sheetmetal cans employed forpacking and transporting liquid paints; and my invention consists in theconstruction and combination of the several parts, as hereinafterdescribed and claimed.

In the drawings, A represents the body of the can, which may be made ofany suitable material, the upper edge of which is bent outward so as toform a lateral flange, e.

B represents a disk or diaphragm of thin or soft sheet metal, preferablyof taggers iron, the circumference of which is equal to or slightlygreater than the flange e of. the body of the can, and which, may have adepression or countersink formed therein by stamping or otherwise,corresponding to the inner circumference of the body of the can, so thatits flange cl shall rest upon the flange e and close the opening intothe body of the can.

G represents an annular ring stamped from sheet metal, having anupward-turned burr or collar, 12, and a downward-turned burr, f, andannular channels 0 and i, of which 0 is sufficientlylarge to admit theflange d of the disk or diaphragmB therein.

D represents an ordinary removable cover, the burr of which fits tightlyover the collar 7) of the opening of the primary cover or annular ring0.

On the right of A, Fig. 1, the different parts of the cover B O D areplaced together as adapted to each other, forming a complete cover ofthe can, and now ready for seaming or uniting to the body of the can.At'g, Fig. 2, the dilferentparts d c f are shown united or seamedtogether.

The method of usin g my can is as follows, viz: Having filled the canwith the desired material, the secondary cover or diaphragm Bis placedover the opening. Over said diaphragm B is then placed the primary coveror annular ring 0, and the two together are united with the body of thecan, preferably by using the machine for which Letters Patent weregranted to me in the United States, October 16, 1877, and numbered196,276.

When it is desired to use the contents of the can the cover D is removedand the diaphragm B cut out closely against the collar 1), through whichthe paint or contents of the can may be used from time to time, asdesired, the cover D forming an almost air-tight joint, and therebyprotecting the contents of the can from contact with the atmosphere.

When desired, the diaphragm B may be constructed from paper or cloth.

After the paint or other contents of the can have been used by theconsumer the can may be used as a fruit-can, or for similar purposes, byreplacing the cover D and sealing the joint by pouring sealing-wax intothe channel 41.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination, with the body A, provided with the flange e,,annularring G, extending beyond the outer circumference of the body A, andprovided with the burrs b and f, and removable cover D, of the diaphragmB, extending to or beyond the outer circumference of the body A, and allunite-d together without the use of solder, substantially as shown anddescribed.

FRANCIS A. WALSH.
